Some interesting pilot accounts i found from various books that survivng WW2 aces have written about their accounts with the P-38 during the war.
Also a interesting one by Adolf Galland:
'P-38s were not difficult to handle in combat. Many, many P-38 pilots are angry with me about this statement, but it's true.'
Adolf Galland
1) "Johannes Steinhoff, Kommodore of JG 77 in North Africa, Sicily and Italy, flying Bf 109s, had this to say about the P-38, 'I had encountered the long-range P-38 Lightning fighter during the last few days of the North African campaign, Our opinion of this twin-boomed, twin-engined aircraft was divided. Our old Messerschmitts were still, perhaps, a little faster. But pilots who had fought them said that the Lightnings were capable of appreciably tighter turns and that they would be on your tail before you knew what was happening. The machine guns mounted on the nose supposedly produced a concentration of fire from which there was no escape. Certainly the effect was reminiscent of a watering can when one of those dangerous apparitions started firing tracer, and it was essential to prevent them manoeuvring into a position from which they could bring their guns to bear."

2) "Oberleutnant Franz Steigler, a 28 victory ace in the Bf 109 with JG 27 in North Africa, said the P-38s "could turn inside us with ease and they could go from level flight to climb almost instantaneously. We lost quite a few pilots who tried to make an attack and then pull up. The P-38s were on them at once. They closed so quickly that there was little one could do except roll quickly and dive down, for while the P-38 could turn inside us, it rolled very slowly through the first 5 or 10 degrees of bank, and by then we would already be gone. One cardinal rule we never forgot was: avoid fighting a P-38 head on. That was suicide. Their armament was so heavy and their firepower so murderous, that no one ever tried that type of attack more than once."P-38 Lightning, by Jeffrey Ethell/The Great Book of WWII Airplanes, Bonanaza Books, 1984Pages 21,22.
3. (Heinz Knoke description of a duel with a P-38 (from "I Flew for the Fuhrer"):
"...At once I peel off and dive into the Lightnings below. They spot us
and swing round towards us to meet the attack.... Then we are in a madly
milling dogfight...it is a case of every man for himself. I remain on the
tail of a Lightning for several minutes. It flies like the devil himself,
turning, diving, and climbing almost like a rocket. I am never able to
fire more than a few pot-shots...."
